I had a dog like Matt's... the only way to get her to take meds was with a small enough piece of steak for her to swallow in one gulp... had to be real careful putting the pill into a cut in the steak. If you accidently touched the pill to the outside of the steak, she'd spit the whole thing out. Peanut butter didn't work... did like Matt's except she'd spit it out with enough PB on it that she never did get to taste it.

The absolute best thing I found was a small ball of bacon grease... just set it on top of the dry food in a bowl...
